What is Broadband?

<div class="zemanta-img"><a href="http://commons.wikipedia.org/wiki/File:OpticFiber.jpg" rel="nofollow" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img alt="Light reflected from optical fiber illuminates..." height="200" src="http://upload.wikimedia.org/wikipedia/commons/thumb/c/c6/OpticFiber.jpg/300px-OpticFiber.jpg" width="150" /></a><span class="zemanta-img-attribution">Image via <a href="http://commons.wikipedia.org/wiki/File:OpticFiber.jpg">Wikipedia</a></span></div><h1></h1><a class="zem_slink freebase/en/broadband_internet_access" href="http://en.wikipedia.org/wiki/Broadband_Internet_access" rel="wikipedia nofollow" title="Broadband Internet access">Broadband Internet</a> service truly is the most used form of <a class="zem_slink freebase/en/internet_access" href="http://en.wikipedia.org/wiki/Internet_access" rel="wikipedia nofollow" title="Internet access">Internet  access</a> because of its high access speeds; it is offered in four  different forms, DSL (or <a class="zem_slink freebase/en/digital_subscriber_line" href="http://en.wikipedia.org/wiki/Digital_Subscriber_Line" rel="wikipedia nofollow" title="Digital Subscriber Line">Digital Subscriber Line</a>), also fiber-optic,  cable, and satellite. The old <a href="http://whatismyipaddress.com/dialup">dial-up</a>  connection is the only non-broadband internet service available, and  even though it is cheaper, most <a class="zem_slink freebase/m/03rlt" href="http://en.wikipedia.org/wiki/Internet" rel="wikipedia nofollow" title="Internet">Internet</a> users are moving towards the  faster broadband Internet connection.<br /><br /><h2>DSL</h2>The DSL (or Digital Subscriber Line) internet service makes its  connection by utilizing unused telephone wires that cause no  interruption to your telephone service. The speed you experience with a  DSL connection varies with your distance from the switching station.  Your speed will be slower the further away you are and faster the closer  you are to the switching station and this may be a deciding factor when  you attempt to select between a DSL line and a cable connection.<br /><br /><h2>Cable<a name="more"></a></h2>The broadband cable connection is provided by the local <a class="zem_slink freebase/en/cable_television" href="http://en.wikipedia.org/wiki/Cable_television" rel="wikipedia nofollow" title="Cable television">cable TV</a>  provider. Here the <a class="zem_slink freebase/en/cable_internet" href="http://en.wikipedia.org/wiki/Cable_Internet_access" rel="wikipedia nofollow" title="Cable Internet access">cable Internet</a> connection speed varies with the  number of users on the service at a specific point in time. Given a  specific geographical area, users of the broadband cable service share  the connection bandwidth which slows the speed the more users are on the  system. This will occur at the peak times for example late in the  evenings after the work day is over when many people will be accessing  the Internet. Somewhat misleadingly, often the cable company would  estimate connection speeds that are based on the thinking that you are  using the service. But that is clearly not the case.<br /><br /><h2><a class="zem_slink freebase/en/optical_fiber" href="http://en.wikipedia.org/wiki/Optical_fiber" rel="wikipedia nofollow" title="Optical fiber">Fiber-Optic</a></h2>The newest broadband service is fiber-optic, which is the fastest  Internet connection thus far. However, this type of <a class="zem_slink freebase/en/internet_service_provider" href="http://en.wikipedia.org/wiki/Internet_service_provider" rel="wikipedia nofollow" title="Internet service provider">Internet service</a> is  still in its infancy as its service areas are quite limited and because  the laying down of the fiber-optic cable takes a while to complete.  Wherever it is available, the cost not only competes with that of DSL  and cable, but it provides a much faster connection than both of those  services.<br /><br /><h2>Satellite</h2>The last and slowest broadband service is provided by satellite.  Although this is a good replacement for dial-up for those people living  in remote rural areas, the installation costs are quite high, but the  ongoing monthly charges are competitive to both cable and DSL.<br /><br />There are many advantages to the DSL and cable broadband service. It  provides greater bandwidth than other Internet access forms, and that  makes it easier for the computer user to multitask with several  applications performing in the background while you surf the web. It is  possible for you to surf the web while listening to audio.<br /><br />The networking of computers in the home is made easier with a broadband connection, by either using wireless or wired modems.<br /><br />The cost of broadband service is higher annually than the cheaper  dial-up version by $100 to $500, but given the advantages and ease of a  broadband connection, it is well worth the cost.<br /><br />A broadband connection allows you to play many popular computer games that rely on a fast Internet connection.<br /><br />Broadband connection, unlike the old dial-up internet connection,  will not engage your phone line when in use. In fact, having a broadband  connection makes it possible for you to obtain an <a class="zem_slink freebase/en/voice_over_ip" href="http://www.wikinvest.com/concept/Voip" rel="wikinvest nofollow" title="Voip">Internet phone  service</a> so you will no longer need the traditional phone line at all.<br /><br />Another great benefit of a broadband connection is that you are  constantly connected to the Internet. You are quickly able to connect  with your work's intranet and email in a matter of seconds.<br /><br />Many people considering between these broadband Internet service  options generally narrow the search to the most popular services which  are DSL and cable. A good approach when researching your options would  be to ask those in the area you are considering, which service they are  using and how it is working for them.<br /><br />Even though cable broadband Internet service offers a speedy internet  connection, this fast speed will not be realized if the connection  itself cannot be relied on. For example, the cable connection you  receive depends on the shared bandwidth, the number of users on the  system at any time, and the latency on the network.<br /><br />The bandwidth is just one factor that determines the Internet  connection's speed. It is a measure of the quantity of data that enters  the network over a period of time, and is measured in bps, or bits per  second. The greater the data flow, the better the network Internet  connection. In broadband connections the supported data rates are  generally 300 Kbps and higher, as opposed to the old dial-up maximum of  53Kbps.<br /><br />Latency is another factor that affects the cable Internet  connection's speed. Latency refers to delays incurred in the network  data processing. A network is described as low latency if it experiences  only small delay times, and high latency if it suffers with long  delays. When the latency becomes excessive, data transmission causes a  bottleneck that prevents addition data from coming through and this  effectively reduces cable's Internet connection bandwidth. So even  though the cable bandwidth of your Internet connection is set, its  effectiveness can be reduced by bottlenecks of data and a high number of  users on the system .<br /><br />Again, with a broadband DSL connection, the connection speed of the  Internet can be severely reduced by the distance a subscriber is located  from the switching station. The further away the subscriber is from the  switching station, the slower the Internet connection.<br /><br />Once installed, a broadband connection is always on. The connection  is maintained with the use of a cable or DSL modem. These connect the  computer to the cable outlet on the wall, in the case of the cable  internet connection; or the DSL modem to the phone line. Only when these  connections become unplugged, will the Internet connection be lost.<br /><br />Unlike the old dial-up service, you will not be dialing a specific  phone number to gain access to the Internet. With a broadband service,  access to the Internet is given by simply double clicking your Internet  browser icon of choice (this is usually on your desktop - Internet  Explorer, Firefox, Netscape etc.); your default web page will open and  you can immediately start surfing the web. The whole process should take  no more than about 10 to 15 seconds, depending on the computer's speed  itself and baring any issues of slowness.<br /><br /><div class="zemanta-pixie"><img alt="" class="zemanta-pixie-img" src="http://img.zemanta.com/pixy.gif?x-id=957bcded-4e80-4bb5-a66b-a5809e108aa7" /><span class="zem-script more-related more-info pretty-attribution paragraph-reblog"><script defer="defer" src="http://static.zemanta.com/readside/loader.js" type="text/javascript"><br /></script></span></div>
